Toshiba MG10 Series MG10ACA20TE Enterprise HDD 20TB 3.5-inch 7200 RPM SATA 6.0 Gbit/s

The Toshiba MG10 Series MG10ACA20TE is a 20 TB, 3.5-inch, 7200 RPM, 6 Gb/s SATA enterprise hard drive designed for high-demand environments. It uses conventional magnetic recording (CMR) within a helium-sealed enclosure to achieve high storage density. It is intended for use in business-critical servers, storage arrays, and network-attached storage (NAS) systems. The drive is rated for 24/7 continuous operation and supports an annual workload of up to 550 TB. It fits into standard drive bays common in modern data centres.

Sequential read and write speeds reach up to 268 MB/s. Toshiba uses Flux Control Microwave-Assisted Magnetic Recording (FC-MAMR) to maintain density while ensuring stability. A 512 MB buffer handles data requests and access patterns. Persistent Write Cache technology helps protect data integrity during sudden power loss. The drive is designed specifically for enterprise environments rather than consumer applications. It is suited for tiered storage infrastructure that requires consistent, high-volume data transfers.

• Mean Time Between Failures (MTBF): 2.5 million hours.
• Sustained transfer rate: Approximately 281 MiB/s.
• Active power consumption: 9.3 W under load, relevant for thermal planning in multi-drive arrays.
• Idle power consumption: 4.38 W.
• Acoustic profile: 32 dB when idle.
• SMART support: Automated drive health monitoring and diagnostics.
